 ### Using JavaScript (non-CRT) implementation of SigV4a
 
+Note: Use of AWS SignatureV4a in the browser (JS implementation) is not recommended, due to the bundle size of the SigV4a signing algorithm code. Consider whether there are other ways to achieve your desired application functionality without the use of sigv4a before installing these packages.
+
 AWS SDK for JavaScript v3 now supports a native JavaScript version of SigV4a that can be used in browsers and Node, and does not depend on [AWS Common Runtime (CRT)](https://docs.aws.amazon.com/sdkref/latest/guide/common-runtime.html). This is an alternative to the AWS CRT version, so you don't need to have both packages together.
 
 If neither the CRT components nor the JavaScript SigV4a implementation are installed, you will receive an error like:
